Potential Impacts of a Green Revolution in Africa – the Case of Ghana AgEcon
Breisinger, Clemens; Diao, Xinshen; Thurlow, James; Al-Hassan, Ramatu M..
Agricultural growth in Africa has accelerated, yet most of this growth has been driven by land expansion. Land expansion potential is reaching its limits, urging governments to shift towards a green revolution type of productivity-led growth. Given the huge public investments required, this paper aims to assess the potential impacts of a green revolution. Results from a CGE model for Ghana show that green revolution type growth is strongly pro-poor and provides substantial transfers to the rest of the economy, thus providing a powerful argument to raise public expenditure on agriculture to make a green revolution happen in Africa.

Land Degradation in Ethiopia: What do Stoves Have to Do with it? AgEcon
Gebreegziabher, Zenebe; van Kooten, G. Cornelis; van Soest, Daan P..
Land degradation is a particularly vexing problem in developing countries; as forests are depleted, crop residues and dung are used for fuel, which degrades cropland. In Ethiopia, the government encourages tree planting and adoption of energy efficient stove technologies to mitigate land degradation. We use data from 200 households in Tigrai, Ethiopia to examine the adoption of new stove technologies. Adoption is an economic decision, related to savings in time spent collecting fuel and cooking, and cattle required for everyday purposes. Results indicate adopters of efficient stoves reduce respective wood and dung use by 68 and 316 kg per month.

Smallholder Household Maize Production and Marketing Behavior in Zambia and Its Implications for Policy. AgEcon
Zulu, Ballard; Jayne, Thomas S.; Beaver, Margaret.
The ability of agricultural policy makers to promote national development objectives requires an accurate and reasonably current picture of what crops farmers grow, what they eat, the importance of various crops in their incomes, and how they spend their money. In Zambia’s case, there is reasonably accurate information on production levels and trends in a specific set of crops grown by smallholder farmers, but very little knowledge of how important these specific crops are in smallholders’ total crop incomes, the importance of crop production in total smallholder incomes (which include livestock and non-farm activities), and how changes in crop prices affect smallholders’ welfare. This paper presents a comprehensive picture of crop production and marketing...

Cotton in Zambia: 2007 Assessment of its Organization, Performance, Current Policy Initiatives, and Challenges for the Future AgEcon
Tschirley, David L.; Kabwe, Stephen.
Cotton is one unquestioned success of Zambia’s turn towards a market economy. After liberalization in late 1994, production rose from 20,000 mt to over 100,000 mt in the 1998 harvest year. After collapsing to less than 50,000 mt in 2000, it has risen steadily, nearing 200,000 mt in 2005. Over 2002-2005, exports of cotton lint were first among all agricultural exports in value, 30% higher than any other agricultural export (Export Board of Zambia 2006). The closest competitor to cotton during this time –raw cane sugar –is primarily produced on large operations, while cotton is almost entirely a smallholder crop. Its potential role in poverty alleviation and food security is, thus, very large. The success of this sector has been achieved despite persistent...

Was There a Credit Crunch in Namibia Between 1996-2000? AgEcon
Ikhide, Sylvanus.
Commercial bank credit is a useful tool for promoting economic growth especially at the early stages of development. It has been observed that between 1996 and the early part of 2000, the growth rate of real credit to the private sector declined significantly in Namibia. This period coincided with observed strong demand for commercial bank loans. There has therefore been public discourse on the possibility of a restriction in the supply of credit by commercial banks and hence the occurrence of a credit crunch in the economy since commercial bank lending capacity did not fall. This paper attempts to provide some evidence in this regard by examining the main determinants of commercial bank credit in the economy and ascertaining if credit has been demand or...

Local and Regional Food Aid Procurement: An Assessment of Experience in Africa and Elements of Good Donor Practice. AgEcon
Tschirley, David L.; del Castillo, Anne Marie.
This report discusses the potential for procurement of food aid in local/regional markets to improve the effectiveness of response to food emergency victims. The paper examines the relevance of local/regional procurement (LRP) to donors and the rationale for using it, reviews LRP’s efficiency relative to in-kind food aid and to local prices in the markets in which it occurs (focusing on Africa), proposes a classification of risks involved in LRP, discusses a range of potential LRP modalities, and closes by proposing a framework of guiding principles, information systems, and operational procedures for responsible and effective LRP.

Population and Sustainability: Understanding Population, Environment, and Development Linkages AgEcon
Clay, Daniel C.; Reardon, Thomas.
The triple challenge of rapid population growth, declining agricultural productivity, and natural resource degradation are not isolated from one another; they are intimately related. However, strategic planning and development programming tend to focus on individual sectors such as the environment, agriculture, and population; they do not explicitly take into account the compatibilities and inconsistencies among them. Farm households and their livelihood strategies are at the core of the intersectoral linkages approach advocated in this chapter. Three key aspects of the population-environment-development debate are discussed: first, the finding that inconsistencies between public and individual household behavior regarding childbearing and family planning...

The Structure and Behavior of Vegetable Markets Serving Lusaka: Main Report. AgEcon
Tschirley, David L.; Hichaambwa, Munguzwe.
Rapid growth in urban populations and renewed growth in per capita incomes in Sub-Saharan Africa (SSA) are creating major opportunities for local farmers by driving rapid growth in domestic market demand for food. At the same time, these trends plus rising income are putting enormous stress on the supply chains that these farmers rely on to respond to this increasing demand: demand for marketed food is likely to grow more than 5% per year on the continent, doubling marketed volumes in 12-14 years. Currently, fresh produce marketing systems are the biggest users of public marketing infrastructure, and have been most severely affected by the lack of investment in these systems across much of the continent. This lack of investment has led to an exploding...

Crop switching as a strategy for adapting to climate change AgEcon
Kurukulasuriya, Pradeep; Mendelsohn, Robert.
This paper examines the impact of climate change on primary crops grown in Africa. An innovative approach is presented that bridges the gap between agro-economic and traditional Ricardian models. We label it a ‘structural Ricardian model’. It first captures the type of crop a farmer will select and then examines the conditional net revenue of that crop. The model is estimated using a sample of over 5000 farmers across 11 countries in Africa. The analysis finds that farmers shift the crops they plant to match the climate they face. Studies that fail to account for crop switching will overestimate the damages from climate change and underestimate the benefits.

Competition between the U.S. and West Africa in International Cotton Trade: A Focus on Import Demand in China AgEcon
Muhammad, Andrew; McPhail, Lihong Lu; Kiawu, James.
We estimate the demand for imported cotton in China and assess the competitiveness of cotton-exporting countries. Given the assertion that African cotton producers are ill affected by U.S. cotton subsidies, our focus is the price competition between the C4 countries (Benin, Burkina Faso, Chad and Mali) and United States in China. Demand estimates are used to project how U.S. prices affect China’s imports by country. In comparing demand projections, results show that the relationship between the United States and the C4 has more to do with how U.S. prices can affect global prices rather than any substitute or competitive relationship in the Chinese market.

AN EXAMINATION OF PROFIT INEFFICIENCY OF RICE FARMERS IN NORTHERN GHANA AgEcon
Abdulai, Awudu; Huffman, Wallace E..
This paper employs a stochastic frontier model to examine profit inefficiency of rice farmers in the Northern Region of Ghana using farm-level survey data. The efficiency index, based on a half-normal distribution of the stochastic error term is related to farm and household characteristics. The empirical results show that farmers' human capital represented by the level of schooling contributes positively to production efficiency, suggesting that investment in farmers' education improves their allocative performance. Access to credit and greater specialization in rice production, are found to be positively related to production efficiency. A farmer's participation in nonfarm employment and being older, however, reduce production efficiency. Farmers...

Does Land Abundance Explain African Institutions? AgEcon
Fenske, James.
I show how abundant land and scarce labor shaped African institutions before colonial rule. I present a model in which exogenous suitability of the land for agriculture and endogenously evolving population determine the existence of land rights, slavery, and polygyny. I then use cross-sectional data on pre-colonial African societies to demonstrate that, consistent with the model, the existence of land rights, slavery, and polygyny occurred in those parts of Africa that were the most suitable for agriculture, and in which population density was greatest. Next, I use the model to explain institutions among the Egba of southwestern Nigeria from 1830 to 1914. While many Egba institutions were typical of a land-abundant environment, they sold land and had...

Accelerating Growth and Structural Transformation: Ghana’s Options for Reaching Middle-Income Country Status AgEcon
Breisinger, Clemens; Diao, Xinshen; Thurlow, James; Yu, Bingxin; Kolavalli, Shashidhara.
Ghana is an emerging success story in Africa and in a couple of years will become the first African country to achieve the first Millennium Development Goal of halving its national poverty rate. The government of Ghana has therefore extended its development vision and recently declared the goal of reaching middle-income-country (MIC) status by 2015. To analyze possible pathways and implications of achieving MIC status, this paper examines other countries’ experiences on their way to becoming MICs and emphasizes the important role of growth acceleration, export diversification, and economic structural change in the transformation process. The paper further analyzes Ghana’s growth options and their structural implications using a dynamic computable general...

Assessment of Kenya's Domestic Horticultural Production and Marketing Systems and Lessons for the Future AgEcon
Tschirley, David L.; Ayieko, Miltone W..
After reviewing trends in the production and marketing of fresh produce for the domestic market in Kenya since 1997, this paper presents detailed information on the structure of the flow of this produce from rural areas to wholesale markets in Nairobi and from those wholesale markets to assorted retail markets. Market shares are estimated by product for geographic areas supplying Nairobi, and for each important wholesale and retail market in the city. It is found that horticultural production for the domestic market is keeping up with rural population growth but not with the much faster urban population growth. The urban wholesaling and retailing system has decentralized dramatically and with little planning over the past two decades in response to lack of...

Spatial Disadvantages or Spatial Poverty Traps: Household Evidence from Rural Kenya. AgEcon
Burke, William J.; Jayne, Thomas S..
The goals of this study are: 1) to determine the relative importance of spatial factors in explaining household wealth; 2) to identify the spatial characteristics of the chronically poorest, the consistently well off, and households escaping from poverty as well as descending into poverty; 3) to determine effects of compound disadvantages on the likelihood of chronic poverty; and 4) to assess the evidence of spatial poverty traps (SPTs). Quantitative analysis is conducted using panel data collected from 1275 households, each surveyed four times with a structured questionnaire over an 11 year period from 1997 to 2007. We identified four distinct groups. The chronically poor are defined as households remaining consistently in the bottom third (tercile) of...

Trends and Spatial Distribution of Public Agricultural Spending in Zambia: Implication for Agricultural Productivity Growth AgEcon
Govereh, Jones; Malawo, Emma; Lungu, Tadeyo; Jayne, Thomas S.; Chinyama, Kasweka; Chilonda, Pius.
This paper assesses the level and composition of the Zambia’s public expenditures in the agricultural sector from 2000 to 2008. By measuring the size of public agricultural expenditures, the study will answer whether the Government of Zambia met CAADP’s target of allocating 10% of national budget to agriculture in 2008. Furthermore, examining what the fund is being spent on will shed light on the extent to which spending contributes to agricultural growth. This review will also characterize the spatial patterns of expenditures across provincial boundaries. The results of this work will hopefully lay a foundation for future analysis of the impacts of public agricultural spending on sector performance.

The Value of Accurate Crop Production Forecasts. AgEcon
Jayne, Thomas S.; Rashid, Shahidur.
Crop production forecasts are widely recognized as an important input into food balance sheets and for anticipating production shortfalls. However, the role of accurate crop production forecasting systems in mitigating food price instability and transitory food insecurity is often under-appreciated. This paper explains how crop production forecasting systems affect price instability and risks, and how they can be improved to stabilize the food system.

Smallholder Income Diversification in Zambia: The Way Out of Poverty? AgEcon
Bigsten, Arne; Tengstam, Sven.
This paper investigates the relationship between income diversification and income change within Zambian smallholder households, and investigates what the constraints of income diversification are in this group. A panel data set of roughly 7000 smallholder farmer households interviewed in 2001 and 2004 is used. Different combinations of the four main income generating activities – farm income, agricultural wage work, non-agricultural wagework, and own-business income – are analyzed.
